| Abstract: | In this work, we report on the controlled fabrication of a self-assembled network of antidots in highly epitaxial La2/3Sr1/3MnO3 thin films grown on top of SrTiO3 (1 0 0) oriented substrates. To promote self-assembly process, it is fundamental to select a unique surface atomic termination of the STO substrates and the appropriate growth conditions. The evolution of the structural and magnetic properties as a function of deposition parameters is analyzed to clarify the growth mechanism leading to the formation of this self-assembled network of antidots. This morphology is of high interest envisaging a new route for the design and fabrication of oxide-based magnetoelectronic devices. |
